Item Anti-plasmodial activity of sodium acetate in Plasmodium berghei-infected mice(DE GRUYTER, 2018-04-10) Abdulkareem, A.O; Babamale, O.A; Owolusi, L.O; Busari, S.A; Olatunji, L.ABackground: Continuous increase in drug resistance has hindered the control of malaria infection and resulted in multi-drug-resistant parasite strains. This, therefore, intensifies the search for alternative treatments with no or less side effects. Several histone deacetylase inhibitors have been characterised to possess anti-malaria activity; however, their further development as anti-malaria agents has not recorded much success. The present study investigated the anti-plasmodial activity of sodium acetate in Plasmodium berghei-infected mice, aiming at finding a better alternative source of malaria chemotherapy. Methods: Thirty female Swiss albino mice were randomly distributed into six groups. Groups A (uninfected control) and B (infected control) received only distilled water. Group C (artesunate control) were infected and treated orally with 4 mg/kg artesunate on the first day, and subsequently 2 mg/kg artesunate. Groups D, E and F were infected and orally treated with 50, 100 and 200 mg/kg sodium acetate, respectively. Results: Sodium acetate significantly lowered parasitaemia (p < 0.05) after 4 days post-treatment, and the parasite inhibition rate of 68.5% at 50 mg/kg compared favourably with the 73.3% rate of artesunate. Similarly, administration of 50 mg/kg sodium acetate improved serum total cholesterol relatively better than artesunate. Our results also revealed that sodium acetate does not interfere with liver function, as there was no significant difference (p > 0.05) in the serum activities of aspartate aminotransferase and alanine aminotransferase in both infected treated and uninfected mice. Conclusions: This study shows that sodium acetate may be a safe alternative source of anti-malaria drugs. Its effect on the serum total cholesterol also predicts its ability in correcting malaria-induced metabolic syndromes.Item Cardiorenal Effects of Pharmaceutical Plant Effluent in Mice (Mus musculus)(Physiological Society of Nigeria, 2019-12) Abdulkareem, A.O; Olafimihan, T.F; Busari, S.A; Garuba, A; Oladipo, S.OMany pharmaceutical industries carelessly handle their effluents and indiscriminately release same to aquatic environment. These effluents often find their ways into surface and ground waters, contaminating public water and thus, serving as a potential threat to animals and human health. In this study, we investigated the cardiorenal effects of chronic oral exposure to pharmaceutical effluent in mice. Thirty male mice (Mus musculus) were randomly divided into groups A F and treated with 0.2 mLs 0.0 %, 2.5 %, 5.0%, 10.0%, 20.0% and 40% concentration (v/v, effluent/distilled water) of the effluent for 28 days, respectively. At the end of the experiment, the animals were sacrificed by cervical dislocation. Activities of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP) were determined in serum and heart homogenate, while uric acid, creatinine and electrolytes (sodium, potassium, bicarbonate and chloride ions) were determined in serum only. Data were expressed as Means ± standard error of mean and values were considered significant at p < 0.05. Results showed that, oral exposure to pharmaceutical effluent reduced (p < 0.05) cardiac ALP, AST and ALT activities as well as serum ALT activity. However, serum activities of ALP, creatinine and uric acid were elevated (p < 0.05). Similarly, there was derangement of electrolytes (potassium, chloride, bicarbonate and sodium ions) in the exposed mice, compared with control. This study has demonstrated that poorly treated pharmaceutical effluent disrupted cardiac and serum enzyme activities, caused electrolytes imbalance and elevated serum uric acid level, suggesting that, drinking water contaminated with pharmaceutical effluent may impair kidney and cardiac functions. Further study, investigating the histology of the kidney and heart of the pharmaceutical effluent-exposed animals as well as mechanism(s) of cardiorenal toxicity of the effluent, should be carried out to exploit its roles in pathogenesis of cardiorenal diseases.Item Effect of untreated pharmaceutical plant effluent on cardiac Na+-K+- ATPase and Ca2+-Mg2+-ATPase activities in mice (Mus Musculus)(Elsevier, 2019-05-06) Abdulkareem, A.O; Olafimihan, T.F; Akinbobola, O.O; Busari, S.A; Olatunji, L.ACardiovascular diseases are major causes of non-communicable diseases (NCDs)-related throughout the world. Water pollution has been linked with the high global NCD burden but no report exists on the cardiotoxicity of untreated or poorly treated pharmaceutical effluent, despite its indiscriminate discharge into the aquatic environment in Nigeria, as in many other locations of the world. Thus, this study investigated the cardiotoxic effect of oral exposure to pharmaceutical effluent in mice. Thirty (30) male mice (Mus musculus) were randomly divided into 6 groups. Group A (control) received 0.2 ml distilled water, while groups B-F were treated with 0.2 ml 2.5%, 5.0%, 10.0%, 20.0% and 40% concentrations (v/v, effluent/distilled water) of the effluent respectively, for 28 days. Significant reductions (p < 0.05) in heart weight and cardiac weight index were observed in the groups treated with 5%, 10%, 20% and 40% concentrations of the effluent, without significant change in body weight. Similarly, 28 day administration of the effluent showed significant decrease in cardiac Na+-K+-ATPase activity (p < 0.05) at concentrations 10% and above, in a concentration dependent manner. However, there was insignificant decrease in cardiac Ca2+-Mg2+-ATPase activity of the exposed mice, when compared with the control group. This study provides novel information on the cardiotoxic effects of oral exposure to untreated pharmaceutical effluent, showing reduced Na+-K+-ATPase activity and decreseased myocardial atrophy. Therefore, drinking water contaminated with pharmaceutical effluent may promote the incidence of cardiovascular diseases. Further studies on the exact mechanistic routes of the induced cardiotoxicity are recommended.
